Cervical Vestibular-Evoked Myogenic Potentials (Cvemps): "Differentiation Of Inter-Neck Emg Symmetry Between Children And Adults", Ellen Jones
Senior Honors Projects, 2010-2019
A cervical Vestibular-Evoked Myogenic Potential (cVEMP) is one of the few objective vestibular diagnostic tests available for pediatric populations. This test evaluates the functionality of the saccule end organ through an inhibitory reflex on the sternocleidomastoid (SCM) muscle that inhibits the level of electromyographic (EMG) activity (Wiener-Vacher, 2013). Because the saccule response is measured as an inhibition of EMG in the SCM, it is imperative that the SCM have a tonic contraction prior to eliciting the response and that the contraction of the SCM is equal on the right and left sides. It is generally accepted that young, healthy adults …

The Feasibility Of Standardized Cognitive Assessments For Vestibular Patients, Brynn Morales
Senior Honors Projects, 2010-2019
Vestibular dysfunction, or impairments in the inner ear and/or brain structures that process sensory information and help control balance, has a high correlation with cognitive deficits, or problems with mental processes. This relationship negatively affects daily activities and quality of life in persons that live with vestibular dysfunction. Though there is sufficient research proving the relationship, few studies have applied that information in ways to better help the population with vestibular dysfunction. The purpose of this study was to assess the feasibility of a cognitive assessment battery (a set of correlated assessments delivered in one session) tailored to measuring performance …

To determine if EMG monitoring or the use of amplitude normalization would significantly reduce the amplitude variability and amplitude asymmetry of the cVEMP in children ages 3 and under, we first needed to create a control group with young, healthy adults to compare the pediatric group to. We also wanted to replicate earlier studies that showed EMG monitoring and amplitude normalization does not have an impact on the VEMP in young, healthy adults. We tested two different positions, sitting and supine. Supine is the optimal position to generate EMG, but we wanted to have control data in case the pediatric …
